Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service (left) and Dr. Scott Ford, avian veterinarian, Avian Speciality Veterinary Services of Alaska (right), take blood samples from a bald eagle (Haliaeetus leucocephalus) captured in the Alaska Chilkat Bald Eagle Preserve. Holding the eagle is Yiwei Wang, graduate student, University of California Santa Cruz. Blood samples are taken of the eagles to study for various things including chemical contaminants such as mercury. Rachel Wheat, graduate student at the University of California Santa Cruz (not pictured) is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. The latest tracking location data of this bald eagle known as "2Z" can be found here: http://www.ecologyalaska.com/eagle-tracker/2z/ . During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.
